Patent DE-2212920-A1 (DE)
Title: Rotary screen printing - using flexible membrane to hold dyestuff under equal pressures
Inventor: HOLZHEY WERNER
IPC: B41F15/42
Filed: 1972-03-17
Abstract: The dyestuff is held in a distribution tube inside the screen cylinder, to be subjected to pressure. A flexible membrane is expanded to equalise the pressure along its length, and force the dyestuff into a sealed zone between the tube and the screen for a lower pressure to apply the dye to the fabric. Designed for pile and structured fabric over 5m wide, equal dyestuff application is achieved without mechanical pressure which could distort the fabric surface structure.

Title: Plastic bags - in strip form from broad tubular film for winding into compact packages
Inventor: ROCHLA KURT
IPC: B31B160/10
Filed: 1972-05-06
Abstract: Broad tubular plastic film is reduced to a number of strips of joined bags, for household use, with side welds and perforations to allow the strips to be separated. The strips travel horizontally, in a vertical stack, through a series of winding stations, where one strips is taken off at each so that simultaneous winding occurs to develop compact packages of wound bag strips. The purpose is to increase the number of bags produced from a variety of material widths, using less plant space.

Title: Continuous cleaning of electrostatic precipitator - weir device ensures steady water stream over precipitation surface and keeps it clean
Inventor: SOMMER WINFRIED
IPC: B03C3/16
Filed: 1972-07-19
Abstract: Precipitation surface of electro static precipator is formed from the annular walls of the air passage. Ionisation electrodes are suspended in the air stream and a high d.c. potential is maintained between these and the walls. Water is fed continuously from the top by a weir device which ensures even water feed down the walls. The top is surrounded by two circular troughs which have a constant water feed and water overflows from these down the walls. On its way down, it scavenges dust from the walls and then leaves from the bottom. This method of cleaning avoids periodic shutdown and consequent atmospheric pollution with dust.

Title: Purifying smelts by crystallisation on cooled surface - using intense flow to prevent inclusions
Inventor: MINHORST ERNST G DR
IPC: B01D9/00

Title: AC voltage halving socket adapter - uses built-in power diode and bridging switch for elimination
Inventor: BRAUN REINHARD PETER MICHAEL
IPC: H01R31/00
Filed: 1974-01-31
Abstract: The socket adapter for halving the A.C. mains voltage has a built in power diode which is arranged in series with the load. The diode may be bridged by a switch to enable the full voltage to be applied to the load. The adapter permits electrical household equipment designed for 110/115 V A.C. to be used on 220/240 V A.C. mains without the conventional use of transformers etc. The low heat generated in the diode is leaked safely away through the contact pins. A switch can be built in the adapter so that full voltage can be rapidly provided. A universal motor, for example, can then be provided with two speeds without further modification.

Title: Fuel injector for diesel pile driver - has nozzle body with offset rod in inlet bore to vortex chamber
Inventor: INENAGA NORIYASU
IPC: F02M65/00
Filed: 1974-08-14
Abstract: Fuel injector is for a diesel piledriver with impact atomisation, and has a nozzle body with a bore connecting to its upstream side, from which end is inserted into the bore a rod which can be rotated about its long axis, or a round rod. The bore downstream of the rod forms a vortex chamber, and has a unit for selectively fixing the angle of the rod w.r.t. the nozzle body. The rod has a flattening along its length, to form a fuel channel from the upstream side of the body to the chamber and offset where it enters the chamber, transversely relative to the rod's axis, so that on rotation of the rod the spatial relation between the outlet to the chamber is altered. A nozzle opening passes from the chamber out of the body, for fuel injection.

Title: Resistance welding wire for packaging sheets has inter. supports - esp. of asbestos cement between end tensioners
Inventor: KIENER JOSEF
IPC: B29C65/22
Filed: 1974-09-07
Abstract: A device constituting part of a thermal welding machine for plastics wrapping comprises a moving support on which a welding wire is tensioned between two supporting arms between these arms, one or more intermediate supports constitute a bearing for the wire. These intermediate supports may be of metal, esp. steel, or of an insulating matl, esp. asbestos cement. A pref. form is that of a triangular plate of thickness approx. equal to that of the wire. Esp. for welding wide sheets, e.g. exceeding 50 cm in width. The normal difficulty encountered by the slackness of a wire of this length is overcome by the use of these intermediate supports. In partic., it is found that asbestos cement provides the necessary supporting strength but constitutes a good insulator.
